Abstract
This study was designed to examine the factors associated with the development of coaching staff cohesion of collegiate head and assistant coaches. In the content validity phase of the investigation, expert input was obtained to provide a theoretical base for the instrument. A 3-factor structure was proposed, and the Coaching Staff Cohesion Scale (CSCS) was developed. The construct validity of the CSCS was investigated with head and assistant coaches (N = 484) of 9 sports from colleges in the eastern United States. Confirmatory factor analysis supported the 3-factor model (Staff Attraction, Shared Values, Staff Unity). The reliability of the CSCS was supported through alpha internal consistency reliability (coefficients ranged from .82 to .94) and composite reliability methods (coefficients ranged from .92 to .98). The theoretical significance and practical application of coaching staff cohesion are discussed; however, continued research on the factor structure of coaching staff cohesion is recommended. In addition, research should be extended to include the influence of coaching staff cohesion on team cohesion, success, and collective efficacy.
